梯形断面曲杆的应力分析与起重吊钩的计算

STRESS ANALYSIS OF CURVED MEMBERS WITH TRAPEZOID SECTIONS AND CALCULATLON OF CRANE HOOKS

  • 摘要: 本文给出了平面问题梯形断面曲杆的极坐标平衡微分方程,按照弹性理论,探讨了梯形断面曲杆一端受集中载荷作用的解,计算了此种截面的各种标准吊钩。本文的研究,既为非矩形断面曲杆提供了一种分析方法,又为梯形断面起重吊钩的设计计算,提供了更为合理的理论基础。

     

    Abstract: In this paper, the authors develop two equations of equilibrium of curved members with trapezoid sections for plane problems in polar coordinates. Then, according to elastic theories, the authors obtain the solutions of the members loaded at one end by a concentrated force and calculate various crane hooks with trapezoid sections. The research gives not only a analysis method of curved members with non-rectangular cross-sections but also a more reasonable theory basis to design and to compute the crane hooks.
